の形状に加圧加熱して賦形する際の成形性が悪
い、耐熱性や機械的強度が小さく高温時や走行中
に車内が減圧状態になつたときに天井材が垂れ下
がる等の欠点を有していた。(Prior technology) Conventionally, laminated sheets made of cardboard or polyethylene foam sheets laminated with vinyl chloride leather have been used for automobile interior materials, especially ceiling materials. They had drawbacks such as poor moldability, low heat resistance and mechanical strength, and ceiling materials sagging at high temperatures or when the interior of the car became depressurized while driving.
これらの欠点を解消するために種々の提案がな

ーが順次積層された自動車用内装材が記載されて
いる。 Various proposals have been made to overcome these drawbacks; for example, Japanese Utility Model Application Publication No. 58-15035 proposes a laminate in which glass fiber-reinforced thermoplastic resin films are laminated on both sides of a styrene resin foam sheet. An automobile interior material is described in which soft synthetic resin foam and vinyl chloride leather are sequentially laminated on one side.
しかしながら上記内装材は比較的重く、コスト
が高く、かつ成形性が不充分であつた。 However, the above-mentioned interior materials are relatively heavy, expensive, and have insufficient moldability.
（本考案が解決しようとする問題点）
本考案は上記欠点に鑑み、軽量で熱成形性がす

て、コストの安い自動車用内装材を提供すること
を目的とする。(Problems to be solved by the present invention) In view of the above drawbacks, the present invention provides an automobile interior material that is lightweight, has excellent thermoformability, excellent heat resistance, high mechanical strength, and is inexpensive. The purpose is to
（問題点を解決するための手段）
本考案は立体網状シートの一面に熱可塑性樹脂
シートが積層され、他面に発泡シートが積層され
てなる自動車用内装材である。(Means for Solving the Problems) The present invention is an interior material for an automobile, in which a thermoplastic resin sheet is laminated on one side of a three-dimensional mesh sheet, and a foam sheet is laminated on the other side.

たシートである。 The above-mentioned three-dimensional reticular sheet has a large number of continuous thermoplastic resin filaments with a diameter of 0.2 to 2.0 mm that are bent three-dimensionally and extend to intersect in some places, and are fused to each other at the intersecting positions to form a large number of ridges between the ridges. This is a sheet with depressions formed therein.

ル、ポリカーボネート等があげられる。又、フイ
ラメントに耐候性、耐熱性等を付与したり着色す

着色剤等が含まれていてもよい。 Any thermoplastic resin can be used as the resin constituting the filament, but those with excellent moldability and elasticity of the filament are preferable, such as polyethylene, polypropylene, nylon, polyethylene terephthalate, polyvinyl chloride, and polycarbonate. etc. can be mentioned. In addition, conventionally known ultraviolet stabilizers, heat stabilizers,
A coloring agent or the like may be included.
フイラメントの太さは細いと機械的強度が小さ
くなり弾性がなくなり、逆に太くなると空〓率が
低下し、嵩比重が大きくなるのでフイラメントの
直径は0.2〜2.0mmに限定されるのである。 If the thickness of the filament is thin, its mechanical strength will be low and elasticity will be lost; if it is thick, the porosity will decrease and the bulk specific gravity will increase, so the diameter of the filament is limited to 0.2 to 2.0 mm.
又、立体網状シートは柔軟であつてクツシヨン
性がすぐれ軽量であることが必要なので厚さに対
する面積重量は50000g／m3以下であつて空〓率
は95％より大である。 In addition, since the three-dimensional reticulated sheet needs to be flexible, have excellent cushioning properties, and be lightweight, the area weight relative to the thickness is less than 50,000 g/m 3 and the porosity is greater than 95%.
立体網状シートの製造は任意の方法が採用され
てよく、たとえば特公昭58−9186号公報に記載の
方法が好適に採用される。 Any method may be used to produce the three-dimensional reticulated sheet, and for example, the method described in Japanese Patent Publication No. 58-9186 is preferably employed.

スチレン−無水マレイン酸共重合体等があげられ
る。 The thermoplastic resin sheet is laminated on one side of the three-dimensional reticulated sheet and is intended to improve mechanical strength, so it is preferably a sheet with rigidity, such as polyethylene, polypropylene, polystyrene, etc.
Examples include styrene-maleic anhydride copolymer.
熱可塑性樹脂シートの厚みは薄くなると強度が
低下し、厚くなると重くなり、成形性が悪くなる
ので好ましくは50〜300μmである。 The thickness of the thermoplastic resin sheet is preferably 50 to 300 μm, since the thinner the sheet, the lower the strength, and the thicker the sheet, the heavier the sheet and the worse the moldability.

い。 The foamed sheet is laminated on the other side of the three-dimensional reticulated sheet to provide heat resistance, sound absorption, etc.
Examples include foamed sheets of polyolefins such as polyethylene and polypropylene, polyurethane, nylon, polyester, polystyrene, and styrene-maleic anhydride copolymers, and polyolefin foams having closed cells are preferably used. Further, the foaming ratio of the foamed sheet is preferably 5 to 40 times.

Furthermore, vinyl chloride leather may be laminated on the foam sheet, or flocking may be applied to the foam sheet.
又、本考案の自動車用内装材は一般に加熱加圧
